savings versus a
traditional call center

A traditional call center is quietly eating your budget

In Vietnam, a traditional line costs 1,500–2,500 VND per minute for a conversation that often lasts under a minute. Multiply that by a team of 20–50 reps calling every day and the invisible monthly phone bill is enough to pay a new hire. That is why more and more businesses are moving to a budget call center on the OMI platform.

Behind every call sits a whole ecosystem: CRM, omnichannel, AI and administration, instead of a patchwork of disconnected tools.

When a customer calls, the agent screen pops up their name, purchase history and notes from the previous call, so nobody has to ask for the same details all over again.

Send ZBS (Zalo Business Solution) template messages, SMS Brandname and follow-up emails from inside the system, triggered by tags, by call behaviour or by an automated workflow.

Omnichannel inbox

Frequently asked questions

Answers about the budget call center

Does a budget call center mean worse call quality?

No. Zalo Cloud Connect calls are real calls carried on Zalo's own infrastructure, in HD audio and video. The Call Center plans still use standard telecom numbers. The low price comes from an optimised cloud infrastructure, not from cutting quality.

What is the difference between the Zalo call center and the Call Center?

The Zalo call center dials out through your Zalo OA (audio + video, 100 VND/minute) and works best when your customers already use Zalo. The Call Center uses your own hotline number to dial any phone number, which suits you if you need a traditional setup with IVR and 1900/1800 hotline numbers. You can run both on the same platform.

Do customers have to follow our Zalo OA to receive calls?

Customers need a Zalo account to receive a call from your Zalo OA. When you call, they see your verified brand name (Zalo OA), so the answer rate is usually higher than for an unknown number. Our specialist will walk you through configuring your OA.

How do Call Center Lite and Pro differ?

Lite is the entry-level plan: calling directly from an IP Phone plus data integration with third-party systems. Pro includes everything in Lite and adds Softphone calling, calling directly from web & mobile app, and an embedded click-to-call button on your website (WebSDK).

Can we use 1800 / 1900 hotline numbers?

Yes. With a Call Center plan you can register 1800, 1900, 024 or 028 hotline numbers in Vietnam. See the Hotline numbers page for details, or let a specialist recommend the number that fits your budget.

What about the one-off setup cost?

The setup fee is charged once and depends on the plan and the scale of the rollout. Leave your details and an OMICall specialist will give you a transparent quote and recommend the most economical option, free and with no commitment.
